For example, in the London Smog Incident in the UK, many people felt discomfort such as chest tightness and suffocation. According to official UK statistics, more than 5,000 people died during the 5 - day period of the heavy fog, and over 8,000 people died in the two months after the fog dissipated. How terrifying it is! Co...

When diesel generator sets operate in high-altitude regions, their performance is significantly affected by environmental characteristics such as thin air, reduced atmospheric pressure, and large temperature variations. To adapt to these special conditions, comprehensive adjustments are required in design, configuration, maintenance, and operation. The specific adaptation measures and their principles are as follows: 1. Diesel generator intake system optimization: Compensating for thin air Turbocharging technology: At high altitudes, the decrease in air density leads to insufficient intake air and incomplete combustion. Turbochargers compress the intake air, increasing its density and ensuring the engine receives adequate oxygen, partially offsetting the power loss associated with rising altitude. For example, power decreases by approximately 8%–12% for every 1,000 meters of altitude gain. Intercooler configuration: After turbocharging, the air temperature rises, causing it to expand a...

There are many types of generators, from small portable generators used as backup power sources for households to large industrial equipment used as primary electricity in remote oil drilling sites. Regardless of the size and function of the generator, they all have one thing in common - they can generate heat. Why does the generator need to be cooled?   Most generators have multiple conductors, and when current passes through them, all conductors generate heat. These heat rapidly accumulates in the system and must be appropriately removed to reduce the risk of damage.   If heat cannot be properly discharged from the system, the coil will quickly be damaged. Many problems, including clearance and balance issues, can arise. But heat can be greatly reduced through various cooling systems. If the generator continues to cool, it is possible to minimize the risk of damage to the  generator  itself. Finally, this will reduce frustration and avoid repair work.   Air co...

The Dingbo series Volvo VOLVO diesel generator set can output its rated power, with a rated voltage of 400 volts and a rated frequency of 50 (60) hertz of alternating current. It is used in factories, mines, construction sites, rural areas, and small towns as fixed or mobile power stations for power and lighting purposes. 1. Main performance of  Volvo diesel generator sets   (1) The Volvo diesel generator set has a static voltage adjustment rate of ≤ 5% under three-phase symmetrical load at 0-100% rated power and power factor COS=0.8-1. It can be adjusted within the range of 95% -105% rated voltage when unloaded.   (2) When the Volvo diesel generator set operates under three-phase symmetrical load conditions, if each current does not exceed the rated value and the difference in three-phase current does not exceed 20%, the set can operate for a long time.   (3) When the output of a Volvo diesel generator set undergoes a sudden or gradual change from 0 to 100% rated po...

What are the reasons for the poor installation quality of diesel generator bearing accessories causing bearing damage? Firstly, there is oil leakage at the top axle oil pipe joint. During the maintenance of the   diesel generator , it was found that there was oil leakage at the top shaft oil pipe joint, and the bearing shells were slightly crushed and peeled, but the damage was not serious. The top shaft oil pipe joint is located on the lower side of the lower tile and is a hose, with a relatively narrow installation space and difficult to operate. This requires special attention to avoid loose connections and potential complications. The temperature probe of the bearing pad has fallen off, and some bearing pads directly monitor the temperature of the bearing pad's black gold layer. The thermal resistor is directly inserted into a hole 2-3 mm away from the bottom of the black gold layer of the bearing pad, and the probe is supported by a bolt pressing spring. If the bolts are not t...

What do you think should be paid attention to when assembling a diesel generator set? The equipment address of the diesel generator set should have excellent ventilation, the generator end should have satisfactory air inlet, and the   diesel generator set   end should have excellent air outlet. The area of the air outlet should be more than 1.5 times that of the water tank. The surrounding area of the diesel generator set equipment should be kept clean to avoid placing items that can cause corrosive gases and vapors such as acid and alkaline in the vicinity. If conditions permit, rescue equipment should be equipped. When diesel generator sets are used indoors, it is necessary to guide the smoke exhaust pipes to the outside. The pipe diameter must be ≥ the diameter of the exhaust pipe of the muffler, and the elbows of the connected pipes should not exceed 3 to ensure smoke evacuation. The pipes should be tilted down 5-10 degrees to avoid rainwater injection. If the exhaust pipe...

In the work of Volvo diesel generator, external factors often play a role through these characteristics of diesel generator, making relevant parts fail. Due to the structural characteristics of the water jacket of Volvo diesel generator, under the action of high temperature, the cooling water forms scale on the outer wall of the cylinder liner, which affects the cooling effect of the diesel generator cylinder liner. The working characteristics of mechanical parts may cause wear of the diesel generator due to friction. During the working process, the piston ring of the diesel generator of Volvo moves in the cylinder at a high speed and in a straight line, causing the cylinder of the diesel generator to wear. During operation, temperature changes are severe, and thermal stress causes deformation and cracks. During the operation of the diesel generator, due to the influence of the ejector pin, the internal stress of the cylinder block and cylinder head of the diesel generator is redistrib...

  Since January this year, the southern region has suffered from continuous rainy weather. Improper handling of diesel generator sets during use is prone to moisture problems, especially the damping of the motors of the generator sets, which has a great impact on the life and work of the generator sets. At this time, the user must dry the damp diesel generator set . For the relevant drying method, the user can refer to the following methods: 1. Short-circuit the three-phase outlet of the stator winding and connect it firmly. 2. Adjust the resistance of the voltage regulating rheostat in the excitation circuit to the maximum value. If the resistance value is not enough, add another resistance to increase the resistance value. 3. Start the generator set , slowly increase it to the rated speed, and then slowly adjust the excitation current. The excitation current is determined according to the damp condition of the generator set, and the short-circuit current of the stator ...
